Frequently asked questions (Beams)
-
I did not provide inputs to any of the loads on the beam. Why are some output graphs being generated?
The dead weight of the beam is always taken into account for the calculations in the XY Plane only. So the results and graphs, calculated for no input on load correspond to the dead weight of the beam on the XY Plane.
-
When should I use the Axially Rigid option?
By default the beam is simply supported type with one of the support as axially rigid. This allows the support to take axial reaction of the input axial forces. Use the Axially Rigid option to make the roller support as axially rigid. You can access the Axially Rigid option from the Supports area on the Design Parameters tab.
-
I want to set the first support as roller support and second support as fixed. What should I do?
All the required inputs defining the support features are given in the Supports area. Use the Support Number option to set it to 2. Check the Fixed option in the Supports area to make the second support as fixed type.
Note:A fixed support is always axially rigid whereas hinge support can be roller or axially rigid type. In one-fixed and one-hinge type support system, the fixed type of support is always axially rigid while the other remains as the roller type.
-
What is the use of Hollow option on the Beam Parameters area?
Section types such as circular, rectangular, and square can have cutout or hole as a design requirement of the section. This cutout or hole is located inside and is symmetric to the section. Use the Hollow option to define the parameters of this cutout.
-
When I edit the Distance parameter from Loads or Supports areas, why do I often get the warning Distance should be less than or equal to Section length?
The maximum value for the Distance parameter is the length of the section. So when you enter a value greater than the section length, the Beam Module gives this warning to request you to review this parameter.
-
What is the difference between the graph options XY Plane, XZ Plane, and Sum on the Calculated Results tab?
The Beam Module takes the load input in Y and Z directions. The calculation results for Y direction load are available through XY Plane option and the calculation results for Z direction load are available through XZ Plane option. The quadratic sum of these results is available through the Sum option.
-
When I click the Calculate button, why do I often get a warning It is necessary to specify torque using at least two forces which are opposite to each other?
This warning is because the sum of all the torque values is not zero. This sum must be zero for a valid torque input.
-
I created a beam using QY CAD Engineering Reference. How do I edit the part to change some of the design parameters?
Editing a part created by QY CAD Engineering Reference is allowed only in the Assembly environment. Right-clicking the part provides an option to start Engineering Reference Beam Module. You can modify the parameters and click the Update button to update the parameters of the component.
